c ..«e..,r.e. i < nnnaSeptember 12.201)6 <br />Orange County SE & SC Ordinance °°~ •••°-~° <br />• Avoid increases in surface runoff volume and velocity by including measures <br />to promote Infiltration to compensate for increased runoff from areas rendered <br />impervious; <br />• Avoid increases in stormwater discharge velocities by using vegetated or <br />roughened swales and waterways in lieu of closed drains and high velocity <br />paved sections; <br />• Provide energy dissipaters at outlets of storm drainage facilities to reduce flow <br />velocities to the point of discharge; these may range from simple rip-rapped <br />sections to complex structures; <br />• Protect watercourses subject to accelerated erosion by improving cross sections <br />and/or providing erosion-resistant lining. <br />2. Exceptions <br />This rule shall not apply in areas other than the University Lake, Cane Creek, and <br />Upper Eno Watersheds where it can be demonstrated that storm water discharge <br />velocities will not create an erosion problem in the receiving watercourse. <br />20 <br />
